Sus304l Sus316l Stainless Steel Elbow Connector 1/2"-24" Gb/T10752-2005 Fittings

SUS304L SUS316L Stainless Steel Shaped Elbow GB/T10752-2005 Elbow Fittings

The application field of the ship-marked elbow: the pipeline system of petroleum, natural gas, chemical industry, hydropower, construction and boiler industries. The basic process of the ship-marked elbow forming technology is: firstly weld a polygonal ring shell or The polygonal fan-shaped shell closed at both ends is filled with pressure medium, and the internal pressure is applied. Under the action of the internal pressure, the cross-section gradually changes from a polygon to a circle, and finally becomes a circular annular shell. The type pipe fitting system integrates the clamp connection, the threaded connection and the opening connection, and develops an economical, economical, fast, simple and reliable mechanical piping system. The advantages of open-hole connection and traditional threaded connection have formed a grooved pipe fitting system with its own characteristics. The rubber seals of grooved pipe fittings, high-elongation ductile iron pipe fittings, and high-strength connecting bolts are produced in accordance with the standard. Each batch of products is tested for chemical and mechanical properties to ensure the safety of fittings and seals during use.

304L stainless steel, also known as ultra-low carbon stainless steel, is a universal stainless steel material that is widely used to make equipment and parts that require good comprehensive properties (corrosion resistance and formability).
304L is a lower carbon variant of 304 stainless steel used where welding is required. The lower carbon content minimizes carbide precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (weld erosion) of stainless steel in some environments.

316L stainless steel is commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipes, exterior materials for buildings in coastal areas, and bracelets and cases for high-end watches. Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

316L is a molybdenum-containing stainless steel. Due to the molybdenum content in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, 316L stainless steel has a wide range of properties. use. 316L stainless steel also has good resistance to chloride attack, so it is usually used in marine environments.
316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing after welding cannot be performed and where maximum corrosion resistance is required.
The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316L stainless steel is also resistant to erosion by marine and aggressive industrial atmospheres.
